Remedial Economics RE: Price Caps
Tuesday, October 13, 2026
At Reason, Veronique de Rugy warns us that we should be terrified of price caps.
Regulars here will already know that this is an immoral and impractical idea that would distort markets and lead to shortages if put into practice.
Same regulars might not know how popular this stupid idea is, though:
A new Wall Street Journal poll finds remarkable bipartisan support for government limits on prices, with 93 percent of Democrats and 83 percent of Republicans supporting capping prescription drug prices. Nearly four in five voters support capping credit card interest rates at 10 percent. And large majorities favor capping child care charges for working families. [bold added]This news should be a clarion call for anyone with half a clue about economics.
Fortunately, de Rugy follows this up with a few brief paragraphs that might help any reasonably intelligent, thoughtful adult who isn't up to speed on economics realize why this idea is even worse than it is popular:
Consider credit cards. A 10 percent interest rate cap sounds lovely. Many Americans pay twice that. Why not simply tell banks that's the limit? Because an interest rate isn't an arbitrary number. It is the price of credit that reflects funding costs, administrative expenses, and, not least, expected default risks.De Rugy does the same quick analyses with two other areas that have politicians talking about price controls. Perhaps these walkthroughs will help people understand that price controls lead to shortages.
Congress can cap the rate, but it can't cap the risk. When the price a lender can charge falls below what the risk costs, lending stops. Lenders turn down applicants, cut credit limits, and close accounts. The borrowers the cap was supposed to protect still need the money. They end up at the payday lender or the pawn shop instead. In other words, interest rate caps hurt the economically vulnerable people they are supposed to help. [bold added]
The piece is far from perfect, most glaringly in that it takes for granted the flawed idea that self-interest is predatory. This limits the usefulness of the piece to serving only as an economic lesson, although it is clear enough that the various price-capping measures out there will, in fact, harm the people they're supposed to be helping.
Price caps are not just stupid, they violate individual rights and, as such, they are also a moral outrage. But getting the word out about the former can be a decent place to start.
